Haha, I didn't even realize the term got inverted by some. Definitely think we should re-normalize on 'scanline' being the part that the CRT actually scans, and the 'scangap' as the non-scanned area between 'scanlines' :)
Ct is not a setting of PCR....you do not set a Ct at the start of a test. Ct is not a sensitivity level. PCR is not a scanner. it does not scan the sample. Are you a POE account?
"The Ct value is inversely proportional to the initial amount of target, 〜When comparing real-time PCR results from samples containing different amounts of target, a sample containing twice the initial amount will have a Ct value one cycle earlier than a sample containing only
Check out what the C and the A stands for and how they are vital in the SCAN procedure.
We have introduced the ability to explain the filters used in the scan, empowering you to master the art of decoding complex scan filters as you navigate thru any scan.
DO YOU KNOW HOW TO READ A CT SCAN? Understand the basics with @georgoff 📽️ app.behindtheknife.org/video/behind-t…
Industrial CT scanners are designed to scan a wider range of materials than medical CT scanners. To address the beam-hardening artifacts you're referring to, we add filtration in the form of copper plates in order to create an X-ray beam with a more uniform energy profile.
CTって現代のやつで分けるとサックリ２種類。 ・多層（マルチスライス）CTスキャナー 一回転するのに0.3秒から0.5秒程度のやつ。 これが一般的。 最新のだと ・超高速CTスキャナー 一回転するのに0.25秒以下。 特に心臓や動く臓器の撮影に有効。 （続く１
In efforts to improve diagnostic services, each Regional Referral hospital is to recieve a CT scanner. CT SCANNERS produce detailed images of many structures inside the body for diagnosis of conditions i.e damaged bones, cancers, heart, lungs and liver diseases, tumors etc.

Is gewoon niet waar. CST wordt enkel gescand om geldigheid te controleren. Gegevens worden nérgens opgeslagen, laat staan verzameld in een centrale database of gekoppeld aan locatie.
#ctscan और बायोमार्कर का दुरुपयोग किया जा रहा है और वे हानिकारक हो सकते हैं, हल्के लक्षण है तो सीटी स्कैन का कोई उपयोग नहीं है। एक सीटी स्कैन लगभग 300-400 छाती के एक्स-रे के बराबर है और इससे युवाओं में भविष्य में कैंसर होने का खतरा बढ़ जाता है : डॉ.रणदीप गुलेरिया #AIIMS
A computed tomography or #CTscan uses X-rays to get 2D and 3D images of the body, showing details of organs which are not available on conventional radiographs. 👉 bit.ly/33eJgut #InternationalDayofRadiology
Should guidelines be evidence-based? The PCR test works by duplicating the genetic material in a sample to a point where a specific genetic sequence is detected. Ct is the cycle threshold. It is the number of amplification cycles needed ... 1/n
If you’re following the news on COVID-19 testing, you may have heard the debate about RT-PCR testing and Ct values leading to false positive results. You may be wondering “How does PCR work, what makes it RT, and what the heck is a Ct value?” A #SciCommSunday primer.
To sum, Ct is inversely proportional to virus load. It is the # of cycles or “zooms” needed to see the virus RNA. If many cycles/zooms needed, it means low viral load input If few cycle/zooms to detect means you high viral load input each +3.3 cycles = 10x lower virus 11/11
So, again, Ct is like zooming in on your computer screen. If you have to zoom a lot, then the thing was small to start with. If you have to zoom a little, then the thing was big to start. In PCR, the ‘thing’ is the starting amount of virus. 10/11
Ct stands for 'Cycle Threshold' In qPCR tests, when the virus RNA enters the test, to detect whether virus RNA exists, it has to get amplified to be seen by the machine, like a ‘zoom’ feature. 2/11
Compelling and scary ProPublica piece about SCAN, a “forensic” analysis technique police and intelligence agents use to “detect” deception in witness interviews. Hawking bad science to law enforcement is unfortunately a booming business in America.
Make the time to read this mind-boggling @bykenarmstrong story about a "forensic" tool that law enforcement--including the FBI & CIA--use even though it's absurd on its face, is not supported by one iota of science, and can lead to wrongful convictions. propublica.org/article/why-ar…
